Answer 1

`\bf \begin{array}{ccll} US~\$&Danish~\$\\ \cline{1-2} 1&2.50\\ 5&d \end{array}\implies \cfrac{1}{5}=\cfrac{2.50}{d}\implies d=\cfrac{5\cdot 2.50}{1}\implies d=12.5`

Answer 2

Option C. 12.50 Danish kroner

Explanation:

It is given that Foreign exchange rate between the U.S. dollar and the Danish kroner is 1 : 2.50

We have to calculate how many Danish kroner in 5 dollar, so we multiply 2.50 with 5.

∵ 1 dollar = 2.50 Danish kroner

∴ 5 dollar = 2.50 × 5 = 12.50 Danish Kroner

Option C. 12.50 Danish kroner
